Who We Are & What We Do

The Green Sports Alliance is the environmentally-focused trade organization that convenes stakeholders from around the sporting world (teams, leagues, conferences, venues, corporate partners, governmental agencies, athletes, and fans) to promote healthy, sustainable communities where we live and play. We are committed to creating awareness and dedicated to creating meaningful change towards a more sustainable future.

We share resources, experience, and expertise to raise awareness of what’s environmentally possible in sports, business, and society. We mobilize sports organizations, communities, athletes, and fans to create sustainable progress and behavior change.


The Green Sports Alliance leverages the cultural and market influence of sports to promote healthy, sustainable communities where we live and play. We encourage the sports industry and its partners to measure, mitigate, and advance their sustainability and social impact.

Sport has a global reach and the Alliance is uniquely positioned to amplify environmental causes and activate passionate fan bases the world over. The Alliance and our members leverage that passion to create meaningful change and provide a universal platform that can catalyze awareness and action.
